I will probably buy the physical copies of the whole series anyway. The first book was OK but I really loved the second book and I hope that they all stay at least that quality.

It does seem like a fun way to read. If I do I definitely have to buy the physical copies because I can't manage that in my Kindle.

I read the first two and now I'm reading the prequel. Apparently that's how the author recommends they be read but it is a hot topic of discussion on Reddit.
